VERTICALLY-SLIDAIBLE INWARDLY SWINGING WINDOW.

Application filed April 27,1925; Serial No. 26,010.

To all whom it may concern:

Be it known that I, OWEN L. DAUTRICK, acitizen of the United States,residing at Detroit, county of Wayne, State of Michigan, have invented acertain new and useful Improvement in Vertically-Slidable InwardlySwinging Windows, and declare the following to be a full, clear, andexact description of the same, such as will enable others skilled in theart to which it pertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification.

My invention relates to an attachment for vertically slidable windowsash, whereby the sash may be swung inwardly for cleaning the outer faceof the glass and that it may also be inclined and secured rigidly forventilating purposes, as shown in the accompanying drawings and moreparticularly described in the following specification and claims. 7

It is well known that in large ofiices or apartment buildings theproblem of cleaning windows is one involving considerableannual expensedue to the time required and hazardous nature of the work.

It is also well known that when vertically movable windows are raisedfor ventillation that the current of air passin directly through theopening creates a draft which is unpleasant and may cause occupants ofthe room to suffer from colds.

The primary object of the present invention is to provide an attachmentforvertically movable window sash whereby the glass may be quickly andreadily cleaned from the inside of the building, thereby greatlyreducing the risk incurred by the party cleaning the windows and timerequired to do thework. A further object of the invention is to providemeans whereby the window sash may be tilted and secured at any desiredangle for ventilating purposes in order that a1r currents may bedirected upwardly above the heads of occupants of the room.

A further object of the invention is to provide suitable metallic guidesattached to the window casing coordinating with elements carried uponthe edge of the sash to facilitate the ready vertical movement of thelatter, thus overcoming any tendency to bind a d al o to teams a dose jin harvest the window casing and the sash frame to prevent the entry ofdrafts common to the ordinary wood sash and easing.

A further object of the invention is to provide detachable means adaptedto be connected with the sash frame and casing to sup-v port one of thesash frames in an approximately horizontal position for cleaning andupon which the other sash frame may rest when cleaning the latter.

A-further object of the invention is to provide means whereby the sashframe may be automatically locked when swung into alignment with thevertically slidable members to which it is pivoted, and whichcoordinates with the member secured to the window casing.

A further object of the invention is to provide means whereby the sashmay be readily removed from the window casing when re quired to makerepairs-there being no stop head to remove or replace.

With the foregoing and other objects in view which will appear as thedescription proceeds the invention further resides in the combinationand arrangement of parts and in the details of construction hereinafterdescribed and claimed it being understood that changes maybe made in theprecise embodiment of the invention herein disclosed without departingfrom the spiritof the same. In the drawings accompanying thisspecification:

'Vifiheait is to gthe sash into.

its lower end. By releasing the' junction with the aperture formed byvthe grommets g, connecting the spring .latch with the channel memberF-are designed w to receive studs projecting from each end of arelatively short pair of supporting bars P, to maintain the sash at anangle for ventilating purposesas indicated in dotted lines in Figure 1.

ing members of the upper sash are similar to those of the lower sash,and it is not considered necessary to duplicate either the drawings ordescription of same to convey W a complete understanding of theinvention.

the glass, the spring latches are released Having now indicated theseveral partsby reference letters the construction and operation of thedevice will be readily understood.

The sash when in normal position is in alignment with the verticallyslidable channel members F, and is secured thereto by the spring latchesG, carried by the channel member entering the. slots B in ,the rL-shapedstrips B, secured to the edges of the sash.

When it is desired to swing the sash into a horizontal position-asindicated in Figure 2for cleaning the outer surface of by pressure uponthe upper ends of the springs G. The sash is then swung inwardly to theposition shown, whereupon the latches Kdue to the action of theirspringsengage the screws L, projecting from the window casings into thespace provided between the walls of the channel members. The channel:members F are thus held against upward movement due to action. of thecounterweights. M The supporting bars I, with theirprojecting studs ateach end, are now engaged through the apertures provided in the re"spective channel members F, and L-shaped bars B, secured to the edges ofthe window sash- To clean-the outer face of the ,upper sash, the latteris lowered and swung inwardly, the respective latches 1K of the uppersash engaging screws L, as in the case of the lower sash. The upper sashhowever rests directly upon the lower s ash, as indicatedin Figure 1.,without the n i of additional supporting bars I.

If it is necessary to remove the sash from the vertically slidablechannel members F It will be understood that the coordinat-,

The sash may then be removed from the window casing.

Upon returning the sash to its normal vertical position the supportingbars I, I, are first removed and the sash swung into alignment with thechannel members-the end wall of the recess B in the L-shaped strips Bforcing the pins K of the spring controlled latches K out of engagementwith the screws L-the spring latches G simultaneously entering the slotB in the strips B,

thereby automatically locking the sash in icertical alignment with thechannel members If it is desired to tilt the windows at an angle forventilating purposes a pair of relatively short supporting bars P fittedat each end with studs are employed to connect the upper ends of thesash with the channel member by inserting the studs in the respectiveapertures provided to receive.

-them"the sash isthus supported at an angle so as to direct the aircurrents upwardly to avoid drafts.

It will be apparent that the angle or L- shaped strips'E, secured to thestile of the window casing serves not only as a guide for the channelmembers F but insures a tight joint between the parts.

Having thus described my invention what I claim is: i

1. -In a device of the class described, a

pair ofvertically movable channel members provided with horizontallyprojecting pivot studs, a vertically slidable sash provided with metalstrips secured to the sash and having bearing recesses receiving thepivot studs and a pa r of swinging hooks provided with recessesintersecting the recesses of the said strips and receiving the pivotstuds for confining the said pivot studs in the recesses of the saidstrips.

2. In a device of the class described, a pair of vertically movablechannel strips provided adjacent their lower ends with horizontallyprojectinghead studs,-a vertically movable sash provided at its sideedges with sheet metal strips extending longitudinally of the sash andprovided at their lower ends with vertical recesses extending upwardlyfrom the lower edges of the said strips and receiving the said studs, a,pair of laterally swinging hooks pivoted to the sash and provided withrecesses arranged to intersect the recesses of the said strips andreceiving the studs to confine the latter in the said recesses.

3. in a device of the class described, a pair of vertically movablechannel members, a

sash pivoted to the channel members and adapted. to swing inwardlytherefrom and means for automatically locking the channel membersagainst upward movement when the sash is swung inwardly, said meanscomprising, a horizontal pin-fixed with relation to the verticallymovable'members and a spring actuated catch arranged vertically andpivoted at its upper endand having its lower end beveled and providedwith a recess for engaging the said fixed pin, and a projection carriedby the catch and extending into 'the path of the sash and arranged to beengaged by the same whereby the catch is disengagedfrom the pin when thesash is returned to its normal vertical position. 10

In testimony whereof, I sign this specification. i
